New method for complex water resources systems reliability evaluation

Abstract

A new methodology for water resources systems reliability evaluation is presented. The proposed methodology considers both: mechanical reliability (probability of pipe failure) and reliability of hydraulic parameters in the nodes and links (pressure, velocity). On the basis of this methodology the model NETREL was developed. This model is useful for determining reliability of systems with different configurations and complexity. Model was analyzed on a water supply system.

U radu je prikazan nov pristup pri određivanju pouzdanosti složenih vodoprivrednih sistema pod pritiskom. Ovaj pristup podrazumeva da se pored pouzdanosti mehaničkih karakteristika elemenata, uzima u obzir i pouzdanost zadovoljavanja hidrauličkih parametara sistema. Metodologija je iskorišćena za formiranje modela NETREL, koji omogućava određivanje pouzdanosti sistema različitih konfiguracija i nivoa složenosti, sa različitim ograničenjima u pogledu hidrauličkih parametara sistema i njihovih vrednosti. Model je analiziran na primeru jednog vodovodnog sistema.
